    A Thor/Delta booster launched from Cape Canaveral successfully placed a Canadian communications satellite, ANIK I, into orbit. This was the 75th Thor/Delta to be launched from the Cape and the first Long Tank Thrust Augmented Thor/Delta to be launched from the Cape with nine strap-on solid rocket motors. It placed the Telestar-A (ANIK) communications satellite in orbit for Canada. Defense Meteorological Satellite Program.
